Definitions

  • This invention relates to a charge control microcomputer arrangement for a vehicle.
  • a clutch device and a speed change device may be arranged between the charging generator and the engine driving the generator.
  • a predetermined (reference) value of the voltage regulator for controlling the output voltage of the generator is externally set, and failures are detected according to data received from various points in the charge system, and the results of this detection are displayed.
  • the output of a charging generator driven by an internal combustion engine of a vehicle or the like is controlled to a predetermined value, so as to charge the battery of the vehicle.
  • the conventional device suffers from a drawback in that, where the predetermined value is controlled during acceleration or deceleration of the engine to thereby control the output of the generator, which is the mechanical load of the engine, it is difficult to control the output externally, and in that the occurrence of problems in the charging system, for instance, when the charging generator generates no power, or is not controlled at all, and the first rectifier output terminal is disconnected, cannot be detected.
  • a conventional charging generator generally employs a drive system wherein the generator is driven, with a certain speed change ratio, through a belt or the like by the internal combustion engine.
  • this system is disadvantageous in that the output current and efficiency of the charging generator vary with the speed of the engine; the output current is insufficient at the low speed operation of the engine, and is saturated at high speeds, thus increasing the loss of power.
  • An object of this invention is to provide a charge control microcomputer device for a vehicle, in which at least some of the above-described difficulties have been eliminated or at least reduced.
  • a charge control microcomputer arrangement for a vehicle, characterised by speed changing means for transmitting the output torque of an engine; a charging generator driven by the output of said speed changing means; a battery charged by an output voltage of said charging generator; a voltage regulator for controlling the output voltage of said charging generator to a predetermined value; an engine controlling microcomputer for receiving data from said engine, to control said engine; a charge control microcomputer for processing engine data from said engine controlling microcomputer and charge system data including terminal voltage data from said battery and generated voltage data from said charging generator, to provide a reference voltage from said voltage regulator, for detecting charging system faults according to said charge system data, and for processing an engine speed signal, comprising at least a part of said engine data, to apply an operating instruction to said speed changing means, so that said charging generator is driven within a predetermined range of revolutions per minute at all times; and a display unit for displaying detection data, including fault detection data, from said charge control microcomputer.
  • An internal combustion engine 1 is installed in a vehicle or the like.
  • a clutch device 2 transmits output torque of the engine 1; an input terminal 201 receives an operating instruction (as to engagement, disengagement or slip) from a charge control microcomputer 8 (described later); a speed change gear 3 is provided for changing the speed of the engine transmitted through the clutch device 2 and transmitting the speed thus changed; an input terminal 301 receives a transmission ratio instruction from the charge control microcomputer 8; and a charging generator 4 is driven by the speed change gear 3.
  • a first rectifier output terminal 401 and a second rectifier output terminal 402 are provided.
  • the figure illustrates a field coil output terminal 403; a neutral point voltage output terminal 404 through which generated voltage data is obtained from the neutral point of star-connected armature coils (not shown); a ground terminal 405; a voltage regulator 5 for controlling the output voltage of the generator 4 to a predetermined value; the regulator 5 having an initial excitation terminal 501, a voltage detection terminal 502, a field coil input terminal 503, a ground terminal 504 and an external control input terminal 505.
  • the figure illustrates a battery 6 which provides battery terminal voltage data; a key switch 7; the aforementioned charge control microcomputer 8; a battery terminal voltage input terminal 801; a second rectifier output terminal voltage input terminal 802; a reference signal output terminal 803 through which an external control reference signal is applied to the external control input terminal 505 of the voltage regulator 5; a neutral point voltage input terminal 804; a transmission ratio instruction output terminal 805 through which a transmission ratio instruction is applied to the speed change gear 3; an output terminal 806 for applying an operating instruction to the clutch device 2; and an input terminal 807 for receiving data from an engine controlling microcomputer 10.
  • the figure illustrates the aforementioned engine controlling microcomputer 10 for receiving engine data, for example, the intake air temperature, r.p.m., crank angle, exhaust gas temperature, air fuel mixing ratio, etc.; from the engine 1, to control the engine 1; an input terminal 101 for receiving a signal from a sensor 11 (described later); an engine control signal output terminal 102; an output terminal 103 for applying data to the microcomputer 8; the aforementioned sensor 11 for detecting the engine state and applying the detection signal to the engine controlling microcomputer 10, an actuator 12 for receiving a control signal from the microcomputer 10, to mechanically drive a part of the engine 1; and a control signal input terminal 121.
  • engine data for example, the intake air temperature, r.p.m., crank angle, exhaust gas temperature, air fuel mixing ratio, etc.
  • the engine controlling microcomputer 8 processes a rotation (r.p.m.) signal, which is one of the engine input parameters received thereby, and outputs this value to the charge control microcomputer 10, which applies an operating instruction as to engagement, disengagement or slip through the output terminal 806 to the clutch device 2, and applies an acceleration or deceleration ratio instruction through the output terminal 805 to the speed change gear 3, so that the charging generator is driven within an optimum, predetermined range of r.p.m. at all times.
  • a rotation (r.p.m.) signal which is one of the engine input parameters received thereby, and outputs this value to the charge control microcomputer 10, which applies an operating instruction as to engagement, disengagement or slip through the output terminal 806 to the clutch device 2, and applies an acceleration or deceleration ratio instruction through the output terminal 805 to the speed change gear 3, so that the charging generator is driven within an optimum, predetermined range of r.p.m. at all times.
  • the charge control microcomputer 8 processes the engine data from the engine controlling microcomputer 10, and charge system data including battery terminal voltage data and generated voltage data, so as to calculate and apply a reference voltage value most suitable for the engine 1 and the charge system to the voltage regulator 6 through the reference signal output terminal 803.
  • the charge control microcomputer detects the occurrence of this problem on the basis of data from various points in the charge system, and applies the detection signal to the display unit 9, so that the problem or fault thus detected is displayed thereon.
  • a clutch device and a speed change device are arranged between the engine and a charging generator and are controlled by a charge control microcomputer which processes engine data, the battery terminal voltage data and the generated voltage data, so that the charging generator is driven within an optimum, predetermined range of r.p.m. at all times. Accordingly, problems caused by the variation in speed of the charging generator, such as an insufficient output in the low speed operation range of the engine, or the increase of loss in the high speed range, are eliminated. Thus, the charging generator can be operated under optimum conditions.
  • the charge control microcomputer processes engine data and charging system data to determine the reference voltage for the voltage regulator. Therefore, the invention has the effect that the most suitable reference voltage is determined for the charging of the battery and the mechanical load can be readily controlled during acceleration or deceleration of the engine.
  • the occurrence ofacharging system problem is detected according to data from various points in the charging system and the results of this detection are displayed. Accordingly, for instance, when the charging generator produces no power or is not controlled at all and the first rectifier output terminal is disconnected, such problems can be detected by the device of the invention, unlike the conventional device.
